GLARE DEFLECTOR Filed Oct. 16, 1929 INVENTOR ATTORNEY Patented Sept. 1,1931 Uhlllfi STATES RALPH W. THIBODEAU, OF QUINCY, MASSACHUSETTS GLAREDEFLECTOR Application filed October 16, 1929. Serial No. 400,052.

This invention relates to a glare deflector for headlamps of automobilesand the like, the general object of the inventionbeing to provide amember adapted to be placed in the lower part of the reflector of thelamp and having upstanding reflector members thereon which deflect therays of light which ordinarily strike the bottom of the reflector to thetop of the reflector so that such rays are prevented from passingupwardly and forwardly and thus blinding the drivers of approachingvehicles and pedestrians.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described illustrated in the accompanying drawings andspecifically pointedout in the appended claim.

In describing the invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure lis a sectional view through a lamp provided with my device.

Figure 2 is a front view of Figure 1.

Figure 8 is a perspective view of the de vice without the ribs orflanges.

Figure 4 is a view of one of the flanges.

In these views, the numeral 1 indicates the body of the device whichtapers from its front end to its rear end and is of arc shape in crosssection, so that when placed inthe reflector 2 of a lamp A, the bodywill cover the lower portion of the reflector. The body formed withthedepending projections 3 which are adapted to be passed through holesformed in the lower part of the reflector and then bent so as to attachthedevice to the said lower part of the reflector, as shown in Figures 1and 2. The rear end of the body may be formed with a substantiallysemi-circular part 4 to fit around a part of the lamp socket and thebulb and the body is also provided with a plurality of slots 5 arrangedin transverse rows to receive the tongues 6 of the strips 7 which arealso ofarcshape, as shown in the drawings. 7

These strips are so arranged that they will reflect the rays of lightupwardly, which rdinarily strike the bottom of the reflector so thatthese rays will be reflected downwardly by the upper part of thereflector, as Lnown in Figure 1. Thus the device prevents any of therays of light being directed upwardly and forwardly so that with thisdevice, glare and blinding of the drivers of approaching vehicles isprevented.

It is thought from the foregoing description that the advantages andnovel features of the invention will be readily apparent.

It is to be understood that changes may be made in the constructian andin the combination and arrangement of the several parts, provided thatsuch changes fall within the scope of the appended claim.

What I claim is 2-- A glare deflector comprising a body taperinggradually from one end to the opposite end thereof and transversely andlongitudinally curved to conform to the contour of the lower portion ofa reflector, projections formed on the edges of the body and extendingangularly thereof to engage the reflector for supporting the body in aslight space relative thereto, an arcuate shaped member formed, on thesmallest end of thebody to engage under the illuminating means of'thereflector, said body having relatively spaced rows of slots arrangedtransversely of said body, arcuately curved reflecting elements arrangedtransversely of the body and in' alignment with the rows of slots, andtongues on the reflecting elements and extending through the slots andbent against one face of said body and spaced from the reflector by theprojections.

llntestimony whereof I aflix my signature.

RALPH W. THIBODEAU.
